Working with demand area definitions

Step-by-step Guide

In InfoWorks WS Pro, demand area analysis provides data that allows users to review the current demand for water and project future potential demand areas.

To define boundary conditions for a demand area:

1. Open the Demand Area Grid.
2. Right-click Demand Area 35 and select Properties.

3. In the properties dialog box, open the Definition tab.

• From the Boundary Conditions group, define the objects to act as boundaries to the Demand Area.
• The Seed Node(s) is a node within the polygon or assigned area code. A trace is carried out, starting from the seed node and continuing until each branch of the trace reaches either one of the boundary conditions selected in the Boundary Condition grid, or the limits of the network. The resultant selection of nodes and links defines the Demand Area.
• Select and Find in the GeoView locates various objects, including Seed Nodes, Bounding Links, the AZNP Node, Transfer Nodes, and the Demand Area itself.
